Remarks

This method is invoked by an internal private method (no public CollectionKind or GetCollectionKind API exists on XamlType).

The default implementation uses the internal CLR reflection. For cases where UnderlyingType is null, the default implementation can use BaseType, if it is available. This behavior indirectly calls LookupCollectionKind recursively to attempt to find a valid base type; it returns XamlCollectionKind.None if no valid base type exists. In general, the default implementation attempts to find the Add method of the underlying type by reflection. If found, the MethodInfo of the Add method is enough information to determine which XamlCollectionKind value should be returned. Otherwise, it returns XamlCollectionKind.None.

Override this method if you are not relying on default internal CLR reflection and are using metadata or other techniques for reporting the XAML type system information or schema information of a type.
